  • [单选题] A decade ago, the idea that the planet was warming up as a result of human activity was largely theoretical. We knew that since the Industrial Revolution began in the 18th century, factories and power plants and automobiles and farms have been loading the atmosphere with heat-trapping gases, including carbon dioxide and methane (甲烷). But evidence that the climate was actually getting hotter was still murky. Not anymore. As an.authoritative report issued a few weeks ago by the United Nations-sponsored Intergovemmental Panel on Climate Change makes plain, the trend toward a warmer world has unquestionably begun. Worldwide temperatures have climbed more than 0.5℃ over the past century, and the 1990s were the hottest decade on record. After analyzing data going back at least two decades on everything from air and ocean temperatures to the spread and retreat of wildlife, the IPCC asserts that this slow but steady warming has had an impact on no fewer than 420 physical processes and animals and plant species in all countries. Glaciers, including the legendary snows of Kilimanjaro, are disappearing from mountaintops around the globe. Coral reefs are dying off as the seas get too warm for comfort. Drought is the norm in parts of Asian and Africa. El Nino (厄尔尼诺) events, which trigger devastating weather in the eastern Pacific, are more frequent. The Arctic permafrost (永久冻土带) is starting to melt. Lakes and rivers in colder climates are freezing later and thawing earlier each year. Plants and animals are shifting their ranges pole-ward and to higher altitudes, and migration patterns for animals as diverse as polar bears, butterflies and beluga whales are being disrupted.
  • What has happened in parts of Asian and Africa?

  • The abnormal weather makes animals move to other areas.

  • 解析:1.细节题。本题的定位在“A decade ago,the idea that the planet was warming up as a result of human activity was largely theoretical""but evidence that the climate was actually getting hotter was still murky…not anymore”即十年前,这种观点只是理论上的,证据是模糊的,而现在再不是了。故选D。 2.细节题。由文中“the trend toward a warmer world has unquestionably begun”,可见该机构的人员认为这种变暖毫无疑问已经开始了。A、B不符合文意,D没有提及。故选C正确。 3.细节题。定位为“worldwide temperatures have climbed more than 0.5℃ over the past century,and the 1990s were the hottest decade on record”,即在过去的一世纪中,世界气温上涨了0.5℃,而20世纪90年代是史上最热的十年。A项错误,C和D项没有提及。 4.细节题。关于亚洲和非洲的描述出现在文章的最后一段。其中提到了干旱,永久冻土带正在消融,河水和湖水的冰冻时间推后,日渐消融,植物和动物都不断向高海拔移动,动物的迁徙被打乱等等。B、C、D都没有提及,故选A,动物正向别处搬家正确。 5.主旨题。文章主要是介绍全球变暖对于地球上生物生活的影响,并没有介绍变暖的原因和责备人类造成了气候变暖,故B和C错误。D项过于偏颇。故选A。
